IMPROVEMENT IN GAS-LIG HTERS.

Specification forming part of Letters Patent No. 201,918, dated April 2,1878; application filed September 12, 1877.

To all whom it may concern.-

Be it known that we, MATTHEW FALOON and DANIEL H. Isnnr'ncnn, both ofBloomington, in the county of McLean, and in the State of Illinois, haveinvented certain new andusefullmprovements in Gas-Lighters; and wedohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of referencemarked thereon, making a part of thisspecification.

Figure l of the drawing represents a side View of our improvedgas-lighter; Fig. 2, a vertical section of the same. Figs. 3 and 4 aredetail views.

This invention relates to improvements in i the class of automaticgas-lighters designed to be operated by a pressure of, gas at the works;and the invention consists in the general construction and arrangementof parts, as will be hereinafter fully described.

In the drawing, A represents a suitable box or case, dividedhorizontally into two chambers, B and G, by an air-tight flexiblediaphragm, D. The lower compartment 0 has connected and in constantcommunication with it a pipe, E, for supplying gas thereto.

F represents a vertical cup, arranged centrally Within the lowercompartment 0, and which is partially filled with mercury, as shown atf, Fig. 2. Grepresents the tube of the large burner 9, having its bottomend inserted in the cup F, and said tube G is centrally and permanentlysecured to the flexible diaphragm D, so as to be raised and loweredtherewith. H represents another cup, partially filled with mercury, andarranged at the side of cup F. This cup H is secured to the tube G orthe diaphragm, so as to be raised and lowered therewith.

I is a tube, having its lower end inserted in the cup H, said tubeextending outside of the case and up to the burner g, or in closeproximity thereto, as clearly shown in Fig. 2. This tube is provided atits upper end witha small burner, t, capable of burning about one footof gas a day, and it is protected by a screen, h, and the hole in thetop of the screen can be omitted, and the entire top can be covered by aperforated plate, or in any other desired ratus occupy the positionshown in Fig. 2.

The tube G being lowered into the mercuryin cup F, so that no gas canenter said tube, and the cup H being lowered so that the tubeI is abovethe mercury contained therein, the gas will flow through pipe I toburner c, which presents a very minute flame. When it is desired-tolight the lampsof an entire city simultaneously, (each lamp beingprovided with one of theabove-described apparatus,) greater pressure isrequired to raise the tube G abov the mereury in cup F, in order toallow the gas to flow through said tube, and this extra pressure issupplied at the gas-works, and in consequence of which the flexiblediaphragm is raised, which raises the tube and burner G g, and also thecup H. As the tube and burner G g is raised it passes out of the mercuryin the cup F, which allows the gas to flow through said tube and burner,and as the gas issues out of said burner, and on the side toward thescreen h, the gas passes through the slit or elongated opening h in saidscreen, and, coniing in contact, is ignited by the minute flame ofburner i. As the tube and burner G grises higher it raises the cup H, sothat the mercury contained therein comes up arolmd the lower end of tubeI, which prevents the flow of gas through the same, andthe'minute flamefrom burner i is extinguished, leaving the gas through large burner gburning brightly.

. The following mechanism is used to prevent the tube G from falling ordropping down by its own weight into the mercury in cup F upon acareless relaxation of gas-pressure or the bursting of a gas-main, andthcrebyextinguishing the light before the desired time: J is a bent rodsecured to the tube G, and this rod is provided with a pivoted catch, j,which engages with the pins 1 on one side of the disk L, journaled tothe bent arm M. The pivoted catch j, as the tube is raised, turns thedisk L, so that one of the two pins 1 on the opposite side of said diskwill catch the arm is upon relaxation of gas-pressure, and hold the tubeG in a raised position. The disk is prevented engaging with one of thepins lof the disk.

'The 'pins '1 and Z are relatively arranged upon the disk L so that uponthe extra pressure of the gas being restored it will again throw up thetube G, so that the second time the tube is allowed to fall it will fallentirely down, and thereby extinguish the light, as above described.When said tube G is lowered, it also lowers the cup H and releases thetube I from the mercury contained therein, so as to allow the gas toagain flow through the tube I, whereby the gas from burner 71 is againignited. It will therefore be observed the parts are so arranged thatthe gas from both burners is for an instant burning at the same time.

When the above-described mechanism is used it will be observed that, inorder to extinguish the light the extra gas-pressure is released andagain restored, and upon being released the second time the light willbe extinguished. Therefore, to'light the lamp, the extra gas-pressureisapplied, and to extinguish the lamp the extra gas-pressure is released,again applied, and a second time released,

which puts the lampout, leaving the minute jet from burneri burning, asbefore described.

We do not desire to be limited to the addi- -tional mechanism abovedescribed for pre 1. The combination, with the case A and stationary cupF, of the automatically vertical adjustable tube and burner G g andflexible diaphragm D, substantially as and for'the purpose specified.

2. The combination, with the tube and burner G g and flexible diaphragmD, ofthe cup H and tube and burner I i, substantially as herein shownand described.

3. The combination, with the case A, of the flexible diaphragm D,mercury-cups F H, gastubes G I, and burners g i, the several partsconstructed and arranged to operate substantially as specified.

4. The combination, with the vertically-adjustable tube and burner G g,of mechanism, substantially as described, whereby the tube and burnerare held in a raised position, substantially as and for the purposespecified.

5. The combination, with the adjustable tube and burner G g, of the rodJ, having pivoted catch j and arm k, and bent arm M, provided withpivoted catch m, and disk L, having pins 1 l, substantially as and forthe purpose specified. i

6. The combination, with the burner i, of the screen h, having a slit orelongated opening, h, substantially as and for the purpose specified.

In testimony that we jointly claim the foregoing we have hereunto setour hands this 3d day of September, 1877.
